Question

Beth has $300 In her savings account. she buys x shirts for $20 each. What is an inequality beth can use tp find how many shirts she can buy and still have more than $100 in her account

Answer 1

let's see:

you do:

20 dollars x 10 = 200 dollars
but 300 dollars - 200 dollars are exactly 100 dollars,
so if you want MORE than 100 dollars, then you do:

20 dollars x 9 = 180 dollars..
300 dollars - 180 dollars = 120 dollars

so your answer is:

she can buy 9 shirts
